Bonus TIPS for Successful Posting

Try a Search First
It is highly recommended that a Search be done on your topic before posting, as many questions have been answered in prior posts. As with any search engine, the shorter the search term, the more "hits" will be returned, but the more specific the search term is, the greater the relevance of those "hits". Searching for "table" might well return every message on the board while "tablesum" would greatly restrict the number of messages returned.

When you do post
First, make sure you are posting your question in the correct forum. For example, if you post an issue regarding Desktop applications on the Mobile & Browser Applications board , not only will your question not be seen by the appropriate audience, it may also be removed or relocated.

The more detail you provide about your problem or question, the more likely someone is to understand your request and be able to help. A sample database with a minimum of records (and its support files, zipped together) will make it much easier to diagnose issues with your application. Screen shots of error messages are especially helpful.

When explaining how to reproduce your problem, please be as detailed as possible. Describe every step, click-by-click and keypress-by-keypress. Otherwise when others try to duplicate your problem, they may do something slightly different and end up with different results.

A note about attachments
You may only attach one file to each message. Attachment file size is limited to 2MB. If you need to include several files, you may do so by zipping them into a single archive.

If you forgot to attach your files to your post, please do NOT create a new thread. Instead, reply to your original message and attach the file there.

When attaching screen shots, it is best to attach an image file (.BMP, .JPG, .GIF, .PNG, etc.) or a zip file of several images, as opposed to a Word document containing the screen shots. Because Word documents are prone to viruses, many message board users will not open your Word file, therefore limiting their ability to help you.

Similarly, if you are uploading a zipped archive, you should simply create a .ZIP file and not a self-extracting .EXE as many users will not run your EXE file.

    Re: Download and view PDF on an iPhone

    Tim is correct, it should be file.to_blob(). I'm sorry about the confusion.

    Also Peter, make sure there is nothing else at all creating output on this page, as it will be output as part of what the browser receives as the PDF file and corrupt it.

      This is the whole page, Lenny:
      Code:
      <!DOCTYPE html>
      <html>
      <head>
      <meta name="generator" content="Alpha Five HTML Editor Version 10 Build 4516-3749">
      <!-- must use in order to make XP Themes render -->
      <meta HTTP-EQUIV="MSThemeCompatible" content="Yes" />
      <meta http-equiv="X-UA-Compatible" content="IE=edge" />
      <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> 
      
      <%a5
      dim PDFFile as c = "C:\Documents and Settings\PG\My Documents\text\Alpha\AlphaFiveProjectDevelopmentGuidelines.pdf"
      Response.MIME_Type = "application/pdf"
      ? file.to_blob(PDFFile)
      %>
      
      
      
      <title></title>
      </head>
      <body>
      <p>&nbsp;</p>
      </body></html>
      But note: the error message says "Adobe Reader" - could there be a conflict w. Adobe?

        Re: Download and view PDF on an iPhone

        Setting Response.MIME_Type to "application/pdf" tells the browser to hand off the whole stream of output to whatever PDF viewer is installed (Adobe Reader in your case). Adobe Reader then expects nothing but a PDF. The parts I have bolded are all output and are considered to be part of the PDF you are sending. They need to be removed.

          Re: Download and view PDF on an iPhone

          OK - so I can try this here, let me confirm the basics, if y'all can humor the new kid?

          1 - I create a page. That code goes on the page.

          And to try this, I'll first test with a known PDF name, test it on the iPhone itself (this will be an alternate button, don't need it to work with Adobe Reader on the desktop)

          2 - Then I'll need to create a button that launches the page, and the button will have to get the name of the PDF from my field.

            Even with that I still get that same error.

              Peter,
              I see Lenny has already replied but just want to let you know I just tested by putting only the following on an A5w page and the pdf displayed.
              Code:
              <%a5
              dim PDFFile as c = "D:\Documents\Data Modeling 101.pdf"
              Response.MIME_Type = "application/pdf"
              ? file.to_blob(PDFFile)
              %>

                  Re: Download and view PDF on an iPhone

                  Here is the generic file-open script I use:

                  EDIT: This first one is for creating a save/open dialog for the download file. Use the second example for opening a PDF.

                  Code:
                  <%a5
                  if eval_valid("filename")
                  	session.filename = filename
                  end if
                  
                  dim filename as c
                  dim fn_folder as c 
                  dim fn_file as c
                  dim session.error_msg as c = ""
                  dim error_msg as c
                  
                  if session.filename = "" then
                  	goto failed
                  	end
                  end if
                  if error_msg <> "" then 
                  	goto failed
                  	end
                  end if 
                  '''no errors
                  path 		= "[PathAlias.ADB_Path]\downloads\\" 
                  if file.exists(path + filename) then
                  	RESPONSE.ADDHEADER("Content-Length: " + FILE_GET_SIZE(Path + Filename))
                  	RESPONSE.ADDHEADER("Pragma: no-cache")
                  	RESPONSE.ADDHEADER("Expires: 0")
                  	response.mime_type = "application/octet-stream"
                  	RESPONSE.ADDHEADER("Content-Type: application/octet-stream")
                  	RESPONSE.ADDHEADER("Content-Disposition: attachment; filename=" + Filename)
                  	RESPONSE.ADDHEADER("Content-Transfer-Encoding: binary")
                  
                  	?file.to_blob(path + filename)
                  
                      else
                  	failed:
                  	session.messagetitle = "Download Problem!"
                  	session.messagetext = "The file was not found, please contact us."
                  	response.redirect("message2.a5w")
                  end if
                  %>
                  And a more simple one just for PDF but with table lookup:

                  Code:
                  <%a5
                  'view pdf

                  	dim cc as c
                  	cc = fto
                  
                  	cc = sql_lookup("::name::conn","document_repository","id="+cc,"documentname")
                  
                  '	cc = urldecode(cc)
                  '	cc = base64decode(cc)

                  	docpath = filename_decode("[PathAlias.ADB_Path]\documents")
                  	filename = docpath + "\\" + cc
                  	if file.exists(filename) then
                  		response.mime_type = "application/pdf"
                  		?file.to_blob(filename)

                            And - it displays on the iPhone. Wahoo!!!!

                            So - next challenge is to dynamically get the correct file name into it from a button on a grid. I'm guessing I have to do a variable?

                            When we get this sorted out I'll be a good doobie and do a little video and/or PDF to wrap it all up nice and neat for the next guy.

                              TaDa! Now it works, somehow the referenced PDF was corrupt! Used another PDF and it works. FWIW, the white space doesn't matter.

                              Thanks for posting your code (again), Steve.

                              And thanks Lenny & Tim.
